Greek farmers are expressing concern over the import of chemically treated tomatoes from Turkey, which they claim is unfair as they have ceased using banned substances due to increased costs, switching to biological preparations. They have written to the institutions, highlighting a recent incident where a shipment of Turkish tomatoes was blocked due to missing phytosanitary documents and questioning the government's allowance of such practices, which they believe disadvantages local producers and poses a risk to consumer health. They are calling for stricter controls on imports and a reevaluation of current agricultural practices.
